摘要

描述了一种确定网络传递函数一阶灵敏度的方法。它使用一种改进的Coates信号流图表示所研究的网络的无源部分,并考虑到网络的求子-求子对对相应节点方程的影响。然后用部分信号流图传递函数表示任意传递函数的一阶灵敏度。这种方法避免了传递函数中相互抵消的问题,简化了灵敏度表达式。一个算例说明了所提出的方法。

Determination of first-order or network transfer function sensitivity by using Coates signal-flow graphs
A method for determination of or network transfer function first-order sensitivity is described. It uses a modified Coates signal-flow graph representation of the passive part of the investigated network having in mind the influence of the ator-norator pairs of the network on the corresponding nodal equations. Then the first-order sensitivity of an arbitrary transfer function can be expressed by using some partial signal-flow graph transfer function. This approach avoids the canceling of each others terms in the transfer functions and simplifies the sensitivity expressions. An example illustrated the proposed method.
